I do what I can on IRC, but I tend to spend my days locked in combat with PHP and Linux system utilities, so as a rule I don&rsquo;t have the faintest idea what&rsquo;s going on with products.

The rest of the figures use a solid ground plane, but with one or more &ldquo;pinches&rdquo; that restrict the return paths.</p>BurnerJeremy on Lawn Sprinkler, Mixed Signal Layouts, and New ProductsBurnerJeremyurn:uuid:e48e686b-36df-734e-811f-1715b9e1c7852009-09-18T16:12:44-06:00<p>Brad Templeton has some really cool panos from the years he&rsquo;s been to BRC.

Idea for that all-in-one device:<br/>
If the device also had the ability&hellip; somehow&hellip; to quantitatively measure the soil&rsquo;s water content then it could not only water until a certain saturation threshold is achieved but <em>not</em> water if the lawn is already over that threshold, say after a rain storm. The water savings there could be significant and you could fine-tune how much water your lawn gets if you&rsquo;re a real stickler for conservation. It seems like several physical measurement locations would be necessary and they would probably need to be separate from the sprinkler heads themselves.<br/>
I&rsquo;m under contract buying my first home right now so in under a month I may have a lawn to call my own. I may want one of these!</p>Calif on Lawn Sprinkler, Mixed Signal Layouts, and New ProductsCalifurn:uuid:cf4b2e5f-0eac-1b6d-0b68-86da5f7636882009-09-18T14:09:44-06:00<p>Nice hair.</p>Nate on Lawn Sprinkler, Mixed Signal Layouts, and New ProductsNateurn:uuid:a4d7f633-e80f-7c3b-9a0e-35c0b4d349c42009-09-18T14:07:27-06:00<p>Ah!

The bit at the very end, though, where it says <em>not</em> to split the analog and digital ground planes lost me. I was following everything up to that point, but that particular leap lost me. Seems like a sentence or two of reasoning was skipped over.<br/>
It sounds like they were suggesting that you would just keep one big ground plane for A &amp; D if you had multiple analog circuits that had to interact with each other as well as interact with the digital side.<br/>
Anybody able to elaborate?<br/>

Sorry to hear your fiddling was not 100% successful. I&rsquo;m working on some code and a board that might be more like the &ldquo;all in one unit&rdquo; that you&rsquo;re talking about. It will auto-sync with the sprinkler (via compass), set up 5 windows of sprinkler position, and then allow the user to input the desired water pressure level for each window. You would set each window pressure by turning 5 trim pots linked to ADCs on the micro. Does this sound like a fun product Sparkfun should sell??

Well done!! This has been a fun project for our team as well. Check us out at Innogation.com and if you find yourself in San Antonio, TX during the first week of December, stop by our booth at the Irrigation Show.<br/>
And yes, Sparkfun has been an invaluable resource in the development of the SmartRotor.</p>Nate on Lawn Sprinkler, Mixed Signal Layouts, and New ProductsNateurn:uuid:0bf037e9-a90e-c11f-dd25-d1ce18252a062009-09-17T08:21:14-06:00<p>Hubble = nice!

I know it is a factor, but when does it become critical?<br/>
I am getting into Mixed signals a lot lately and so far (knock on wood) haven&rsquo;t seen an issue.<br/>
The signals I am working with however are low freq, basic Analog DC type signals. So I assume it&rsquo;s not critical to the signals I have been working with.<br/>
I can see however how the higher the freq the more important it becomes.</p>Landon on Lawn Sprinkler, Mixed Signal Layouts, and New ProductsLandonurn:uuid:8c88a5c9-0253-6f74-2a56-53c3ff8df92b2009-09-16T18:34:28-06:00<p>Nate, dude, you gotta tell us the story about your hair.

The catalyst, I have an existing in ground irrigation system that was with my home when I purchased it. In the past month I&rsquo;ve had to dig into the ground twice, once to fix a cap on the line that blew off and another to fix a head that was jammed and wasn&rsquo;t popping up. Both times I ended up fiddling with sprinkler heads and nozzles trying to figure out the optimal patterns to cover the most area without wasting water. And after the second problem where 2 hours worth of tweaking got me to about a 70% solution and I need to control the pressure to get that other 30%.<br/>
It would be nice to have an all in one unit that you could program with a 2d profile of your yard (or a given area) at a fixed point and have the sprinkler head rotate and modulate so that the entire area is covered and little more.</p>Nate on Lawn Sprinkler, Mixed Signal Layouts, and New ProductsNateurn:uuid:7e1bcedf-82ad-84f3-d4e1-ddc7852bd1182009-09-16T15:32:42-06:00<p>Thanks for the heads up!
